Ground Penetrating Radar Reverse Time Migration Processing Based on MultiResolution of Wavelet

Abstract:

Based on Maxwell equation,multiresolution of wavelets reverse time migration algorithm of GPR is derived according to the wavelet multiresolution decomposition theory and central difference format.The corresponding processing program is developed thereafter.Comparison of the radar data processing outcome by regulations Kirchhoff integration migration and 15° finite difference migration algorithm shows that the multiresolution of wavelets reverse time migration algorithm of GPR enjoys the merits that reflection wave returns to original position more accurately,migration outcome is more precise,imaging effection is all the better,there is no limitation to migration angle of inclination,and it is highly adaptable to noise.It can be enhanced dramatically by the algorithm,and can better serve the geological explanation of GPR section.
